xpdf, a program for viewing and printing PDF files


Xpdf is an open source viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities.

       xpdf - Portable Document Format (PDF) file viewer for X (version 3.01)
       xpdf [options] [PDF-file [page | +dest]]
       Xpdf  is a viewer for Portable Document Format (PDF) files.  (These are also sometimes also
       called ´Acrobat' files, from the name of Adobe's PDF software.)  Xpdf runs under the X Win-
       dow System on UNIX, VMS, and OS/2.
       To run xpdf, simply type:
              xpdf file.pdf
       where  file.pdf is your PDF file.  The file name can be followed by a number specifying the
       page which should be displayed first, e.g.:
              xpdf file.pdf 18
       You can also give a named destination, prefixed with ´+'  in  place  of  the  page  number.
       (This is only useful with PDF files that provide named destination targets.)
       You can also start xpdf without opening any files:

Help, Manuals and Documentation

help commands:
man xpdf

further information:
See the man page man xpdf and for frequently asked questions.


The local configuration should be set up: Copy the sample-xpdfrc file to /usr/local/etc/xpdfrc. You'll probably want to edit its contents (as distributed, everything is commented out) -- see xpdfrc(5) for details.

License Text

Xpdf is licensed under the GNU General Public License (GPL), version 2. In my opinion, the GPL is a convoluted, confusing, ambiguous mess. But it's also pervasive, and I'm sick of arguing. And even if it is confusing, the basic idea is good.

In order to cut down on the confusion a little bit, here are some informal clarifications:

  • I don't mind if you redistribute Xpdf in source and/or binary form, as long as you include all of the documentation: README, man pages (or help files), and COPYING. (Note that the README file contains a pointer to a web page with the source code.)
  • Selling a CD-ROM that contains Xpdf is fine with me, as long as it includes the documentation. I wouldn't mind receiving a sample copy, but it's not necessary.
  • If you make useful changes to Xpdf, please make the source code available -- post it on a web site, email it to me, whatever.

If you're interested in commercial licensing, please see the Glyph & Cog web site:
